[PATCH v1] merge - rename a shadowed variable in cmd_merge

[Edmundo Carmona Antoranz <eantoranz@gmail.com>]

variable ret used in cmd_merge introduced in d5a35c114ab was already
a local variable used inside a for loop inside the function.

for-local variable is being renamed to ret_try_merge to avoid shadow.
